Transcript of Water Scarcity and Population Explosion

The term population explosion is a rapid increase in population attributed especially to an accelerating birthrate, an increase in life expectancy. Our current world population is over 7 billion and as mentioned before, there is only so much water to support 6 billion people. Population Explosion Facts The world population is growing by about 0.8 percent, or almost 80 million people, per year.The fact that our supply is not infinite has dire implications on our world population of nearly 7 billion people and growing.The global water consumption rate doubles every twenty years, a pace that is double the rate of population growth.

Water availability in different countries This is a video explaining the rapid population growth of earth Some Questions to think about? 1. In the future, what can we do to prevent or slow down water scarcity?

2. What are some ways which we can slow down or discourage population growth? Did you know??? Around 700 million people in 43 countries suffer today from water scarcity.By 2025, 1.8 billion people will be living in countries or regions with absolute water scarcity, and two-thirds of the world's population could be living under water stressed conditions.With the existing climate change scenario, almost half the world's population will be living in areas of high water stress by 2030, including between 75 million and 250 million people in Africa. In addition, water scarcity in some arid and semi-arid places will displace between 24 million and 700 million people. Sub-Saharan Africa has the largest number of water-stressed countries of any region. How does it happen ? Water scarcity occurs when the demand for water from all sectors (agriculture, cities, environment, etc...) is higher than the available resource.There is enough freshwater on the planet for six billion people, but it is distributed unevenly and too much of it is wasted, polluted and unsustainably managed. Water use has been growing at more than twice the rate of population increase in the last century, and, although there is no global water scarcity as such, an increasing number of regions are chronically short of water. What is population explosion? In simple terms water scarcity is the shortage of fresh water for use. Water scarcity is both a natural and a human-made phenomenon. The amount of water on our planet never changes, it just changes state. However, what is changing is population. With populations rising in countries, water scarcity is among the main problems to be faced by many societies. Already 1.2 billion people around the world are affected by this problem. This is a video about water scarcity Water isn't evenly distributed Only 20% of the global population has access to running water and over 1 billion people do not have access to clean water. Here in Canada, we are so lucky to have an abundant supply of fresh water. We feel like we have an unlimited supply, when we don't. This is the reason why we misuse it. According to the World Water Development report, half of the population will be living in regions of high water stress by 2030. We need to find solutions so that we will have enough of this resource for future generations.
